CREAM sIrHoN.

' Application filed December 30, 1924. Serial No. 758,815.

To all whom it may concern:

Be it known that we, LEE 1). PIERCE and EDWARD RV. AUsTEN, citizens of the United States, and residents of Fulton, in the county of Oswego and in the State of New York, have invented a certain new and useful Cream Siphon, of which the following is a specification.

This invention relates to siphon attachments for bottles, particularly milk bottles, whereby the cream can be withdrawn from the top of the bottle, and has for its object a particularly simple, eflicient and sanitary means, which is readily cleaned after being used for starting the siphonic action through the tube.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference had to the accompanying drawing which is a vertical sectional view of this siphon, the same being shown as applied to a milk bottle.

This siphon comprises a siphon tube having one arm thereof adapted tooextend into the bottle, with its apex extending across the top edge of the bottle, and having its outer arm provided with an elongated suction sleeve or cap mounted thereon and movable off the end of the tube, the cap enclosing the tube a sufficient distance, so that, when the cap is withdrawn oil the tube the liquid in the bottle when full or nearly so, will be raised over the apex of the siphon by the suction caused as the cap is withdrawn from the end of the siphon tube.

1 designates the siphon tube, here shown as having an arm 2 designed to'extend into the bottle, as a milk bottle 3, to, approximately the lower level of the cream which accumulates at the top of the bottle, the tube also'having an outer arm here shown as deflected inwardly and then outwardly, so that it will engage near its angle 1 with the outer face of the bottle or when the cap is mounted thereon, the cap will engage the outer face of the bottle and thus hold the.

tube from tilting.

When the tube is inserted the proper distance in the neck of the bottle,-the apex 4 thereof will extend across the top edge of the bottle.

5 is the elongated cap or sleeve having a head 6 at its outer end, this cap slidably fitting on the outer end portion of the siphon tube, and enclosing the tube a sufficient distance back from its lower end to create a suction for a sufiicient length of time as the cap is withdrawn off the end of the tube, to lift the cream around or over the apex of the tube and thus start the flowing of the cream.

. The tube is, usually formed of glass, and

the cap is formed. of wood, metal, hard rubber, or other suitable material forming a sliding substantially air tight joint with the glass tube.

In operation the siphon tube is placed in the neck of the bottle and the cap quickly withdrawn from the end thereof. starting the cream to flow through the siphon tube, and obviously it will continue to flow until the level of the liquid is below the lower end of the inner arm of the tube.

After being used the cap and tube are readily cleaned, so that, the device can be easily kept clean and sanitary.

Owing to the use of a cap no packing or specially formed rubber bulbs or pistons are required, and further owing to the cap a sanitary device is produced which is extremely economical to manufacture. The cap may be formed cylindrical or polygonal in cross-section and the outer surface used for printed or advertising matter.

What we claim is:

A siphon attachment for bottles, comprising a siphon tube having a uniform outer diameter throughout its length, and an elongated cap enclosing the outer end of the tube and having direct contact throughout its length with the tube for making a sub stantially air tight joint between the cap and the tube whereby when the cap is with.- drawn from the end of 'the tube sufficient suction is created to draw a liquid over the apex of the tube.

In testimony whereof, we have hereunto signed our names, at Fulton, in the county of Oswego, and State of New York, this 4th day of December, 1924:.

LEE D. PIERCE. EDWARD W. AUSTEN.
